PORTLAND, Ore. (AP) — Another top official of Oregon’s troubled health insurance exchange has resigned.

Cover Oregon officials said chief operating officer Triz delaRosa relinquished her duties on Tuesday but will remain as an adviser until May 16.

The position was filled by Mark Schmidt, a consultant with a Portland firm that specializes in turning around struggling businesses.

Clyde Hamstreet, that firm’s founder, took over Cover Oregon’s executive director role earlier this month.

DelaRosa is the fifth official connected to the development of Oregon’s exchange to resign.

Gov. John Kitzhaber directed Cover Oregon’s board to replace her and another official in March, after an investigation found state managers repeatedly failed to heed reports about problems that prevented the exchange from launching.
